This is a known issue in 1.1.23 that is resolved in later releases
of CUPS.

This is caused by packet loss - cups-polld in 1.1.23 would relay all
printers at once, overloading the cupsd process and resulting in many
of the update packets getting lost.

> I´ve tried to raise the value for timeout to 3600 seconds, but its still removing the queues. Is there any way to tell CUPS not to remove queues due to timeout. The master server never removes the queues.

About all you can do is set the timeout to a very large value.
